This is my feet and legs selfie standing firmly on the medieval rocky road walls of Dubrovnik, Croatia, feeling grateful that these extraordinary limbs have carried me through 45 days of walking or climbing up and down stairs and hillsides. Three years ago, my legs were uninjured and I walked these walls with confidence. Well, today, I continued to walk these walls with confidence and I am utterly grateful. Goodbye Croatia, hello Texas.
